Atlas 5 rocket rolled out to launch pad

The United Launch Alliance Atlas 5 rocket is hauled out to the pad this morning, riding the rails from its assembly building to Cape Canaveral's Complex 41 for the final day-and-a-half of preparations to fly the massive new communications satellite into orbit for the Defense Department.

Tomorrow's ascent with the U.S. Navy's Mobile User Objective System 1 satellite will begin constructing a new space-based constellation for global mobile communications and replacing the military's aging Ultra High Frequency (UHF) spacecraft fleet.
